A nurse is working on a pediatric cardiology unit and has four patients, each with a different congenital heart defect. Match the congenital heart defect with the correct hemodynamic classification.
Hypoplastic left heart syndrome - Decreased pulmonary blood flow.
Tetralogy of Fallot - Obstruction to blood flow.
Atrial Septal Defect - Increased pulmonary blood flow.
Aortic Stenosis - Mixing of blood flow.
Correct Answer : A,B
Choice A:
Hypoplastic left heart syndrome - Decreased pulmonary blood flow.
Choice B:
Tetralogy of Fallot - Obstruction to blood flow.
Choice C rationale:
Atrial Septal Defect is incorrectly matched with its hemodynamic classification. ASD results in increased pulmonary blood flow due to the shunting of oxygenated blood from the left atrium to the right atrium.
Choice D rationale:
Aortic Stenosis is again not accurately matched. Aortic stenosis causes obstruction to blood flow from the left ventricle to the aorta, impacting systemic circulation.

Correct Answer is D
Explanation
Choice A rationale:
Assessing the infant's ability to roll over is unrelated to the situation. The nurse's focus should be on safely retrieving the nasogastric tube without leaving the infant alone.
Choice B rationale:
Using a nesting pillow is not appropriate in this scenario. The nurse should prioritize getting the nasogastric tube rather than introducing unnecessary items into the crib.
Choice C rationale:
Putting the side rail all the way up might hinder the nurse's ability to access the counter and the nasogastric tube. It is not the most effective action in this situation.
Choice D rationale:
Calling for assistance ensures that the infant's safety is maintained while the nurse retrieves the nasogastric tube. Leaving the infant unattended increases the risk of harm, so involving someone else is the appropriate action.
Correct Answer is C
Explanation
Choice A rationale:
Baclofen from an intrathecal pump primarily affects muscle tone and spasticity, not seizure medications .
Choice B rationale:
Baclofen use generally leads to a reduction in dystonia , not an increase. It's used to manage spasticity, not exacerbate it.
Choice C rationale:
The correct answer. Baclofen administered via an intrathecal pump is intended to reduce muscle tone and spasticity, improving mobility and comfort for patients with conditions like cerebral palsy.
Choice D rationale:
Baclofen doesn't typically cause decreased mobility . In fact, its use is expected to enhance mobility by reducing spasticity.
